Full textI present a study of electron transport in arrays of gold nanoparticles formed by the Langmuir –Blodgett method. In weakly coupled arrays, electronic transport is due to sequential tunnel diffusion described by activated laws. By increasing the coupling between the nanoparticles, a diffusion regime controlled by cotunneling is reached, where electronic transport is described by the Efros-Shklovskii law. The nanoparticles, which present various electronic properties, allow considering the study of their electronic spectrum in the regime of strong quantum confinement. To study the electronic spectrum of individual nanoparticles, we developed a setup for vacuum projection of nanoparticles which allows fabricating efficiently single nanoparticle devices. This setup has been tested with the observation of Coulomb blockade in gold nanoparticles. Then, this setup has been applied to the fabrication of single nanoparticle devices with magnetite nanoparticles. These circuits allowed establishing the out-of-equilibrium phase diagram of the Verwey transition as function of temperature and electric field. We have also studied the evolution of the tunneling current in the field emission regime through thin films of PMMA deposited on two electrodes separated by a distance of the order of ten nanometers. We observed that the scission of polymer chains leads to a measurable additional electronic noise

Full textThe extensive use of nanomaterials has raised awareness about health issues and their fate in the environment. That is why they are now subject to regulation that has imposed their traceability from their manufacturing to their distribution as the establishment of their characteristics (chemical composition, size, agglomeration state, shape ...). A characterization routine for nanoparticles in suspension was developed. Transmission Electron Microscopy (TEM) fulfills most of the criteria cited before by combining imaging and spectroscopy techniques. Three sample preparation methods were optimized to ensure high quality results : a dry process, rapid freezing to vitrify the sample and the use of an textit{in-situ} liquid TEM holder to prevent any preparation artefact (no phase change). To obtain quantitative analysis, a comparison was made between Dynamic Light Scattering (DLS), Multi-Angle Light Scattering (MALS), with and without a fractionation system (AF4), and TEM. To support this work, two nanomaterials were analyzed. The first one is a nanoemulsion composed of lipid nanoparticles stabilized by surfactants used as nanocarriers for drug delivery. Their stability after protein interaction was investigate and some size variations were observed. The second material is a powder composed of titanium dioxide nanoparticles used as UV filters in sunscreens. These nanoparticles were analyzed before and after interaction with UV radiation in a climatic chamber to confirm their stability. The different protocols developed in this PhD may be used for the analysis of other nanomaterials

Full textThe topic of this thesis is about the structure of smectic topological defects and the self-assembly of spherical gold nanoparticles trapped inside and outside these defects. We prepare liquid crystal films (about 200 nm thickness) which create arrays of perfectly oriented defect lines (mostly dislocations). These defect lines can trap nanoparticles with a diameter varying from 4 to 9 nm and induce an organization into chains oriented along the direction of the defects. This arrangement of gold nanoparticles is responsible for the anisotropy of the optical response (localized surface plasmon resonance) associated to an electromagnetic coupling in the direction of the chains which allows to control the extinction with the polarization of the light. An increase of the concentration of nanoparticles leads to an evolution of their organization from chains to hexagonal monolayers with the (10) direction parallel to the defect lines suggesting a growth mechanism around the chains. Furthermore, we reveal a compression of the nanoparticles both in the chains and in the 2D structures which we explain with a model of the interactions between nanoparticles. This model is based on a new estimation of the structure of the liquid crystal matrix by synchrotron X-ray diffraction measurements which contains a rotating grain boundary with two dislocation lines at its summit (Burgers vectors 6 and 4) and another one near the substrate (Burgers vector 2). The elastic deformations of the smectic layers close to the defects are estimated. Finally, we show that the self-assembly of the nanoparticles can be modified through heating treatment

Full textThis work describes how to create and characterize metallic nanoparticles. Two major steps are required to obtain such nanoparticles. The first one consists in the making of thin layers using a sputtering method. To evaluate the efficiency of this method, we have carefully analyzed how various parameters may affect the deposit. The set of parameters includes the distance between the target and the substrate, the current and the time of deposit. We have shown that these parameters are crucial regarding the morphology of the layer, its porosity as well as its optical and electrical properties. The second step consists in the preparation of the nanoparticles solution using a new method using ultrasounds. By characterizing the solutions, we have carefully checked the properties of the nanoparticles and the efficiency of the method. The tools and the methods we have used are based on imagery (MEB, TEM, AFM), optical and spectroscopic characterization and dynamic light scattering. First results are also presented concerning targeted therapy. The aim is to use the nanoparticles we have made to destroy tumor cells. An experimental setup has been used to evaluate the capabilities of the nanoparticles to increase their temperature under magnetic field activity using a field of 15 mT at high frequencies (200 kHz)

Full textAdditives with tribological action (MoDTC and ZnDTP) used at present are organic molecules containing sulphur and phosphorous. For environmental reasons, it is important to reduce or eliminate the presence of these two elements in oil. In this study, we are being interested in nanoparticles with closed structure (spherical, cylindrical) as potential substitutes of these additives. Their size, nanometric, enables them to enter easily the contact and their structure, closed, confers a great chemical inertia to them. Fullerenes of MS2 show very good friction reducing and anti wear properties. Their lubrication mechanism is based on the release of hexagonal MS2 sheets in the contact area. Tribological properties of carbon nanotubes depend on several parameters (number of wall, presence of catalyst). A structural modification of nanotubes inside the contact area is necessary

Full textThe@replacement of aggressive organic molecules by mineral particles which could reduce friction and wear has been the main idea of this research work. The aim is thus to reduce product concentration in lubricant and pollutant gas émission. Boundary lubircation regime is well suited for this type of study in particular for being discriminative in tested nanoparticles efficacy. We are firstly being interested in an anti-wear additive named Overbased Calcium AlkylBenzen Sulfonates and we have shown then friction reduction capabilities of inorganic-fullerene (IF) MoS2 nanoparticles. Physical and chemical studies of nanoparticles by EFTEM, XPS XANES, ToF-SIMS, Raman spectroscopy, XRD, EXAFS have been necessary to understand mechanisms induced by friction

Full textThe objective of this work is to develop a technique for separating nanoparticles from liquid media. The literature has shown the potential hazard of nanoparticules and a large quantity of the nanosilica release has been entering in water resources. Tests flotation separations are carried out without additive, in the presence of AlCl3, CTAB, and trying to change the surface charge of the bubbles. These tests are not very conclusive. Flotation has been observed, but only when the additive has led to the formation of flocs which have themselves been floated. The results of tests with additives showed that the interaction between heterocoagulation (flotation) and homocoagulation is very important, leading to the study of coagulation under the effect of AlCl3 and CTAB. The results revealed complex mechanisms of coagulation, because the particle size plays an important role. For each observed phenomenon, a mechanism has been proposed, trying to link the observations to modeling mechanisms of aggregation. From the standpoint of the separation process, coagulation followed by sedimentation to separate the silica nanoparticles with remarkable efficiency (decrease of 99% of the turbidity)
